You are able to rotate any function by an arbitrary angle around the origin using the formula, $$y\cos\theta-x\sin\theta=f(x\cos\theta+y\sin\theta)$$You can also do similar rotations for polar graphs, or multivariable functions; however, what would the actual purpose of doing so be? Possibly making a certain problem easier to evaluate or does it have some application in real life?

It's used in almost every field of physics and engineering. You write a matrix associated with the rotation and you apply it to your vector.
